FORD:
1993 PROBE

ISSUE:
A metallic "ticking" noise from the engine valve hydraulic lash adjusters may occur after a hot soak. This noise may be heard under the following conditions:

^ When returning to idle speed after freeway driving

^ After a hot soak at idle speed just after restarting

This condition may be caused by the factory oil becoming contaminated and is usually noticed in the first 1000-3000 miles (1600-4800 km) of new vehicle operation. The contamination can cause the oil to have increased foaming characteristics.

ACTION:
Replace the engine oil and oil filter. Refer to the following service procedure.

NOTE:
THE FOLLOWING TWO SYMPTOMS ARE NORMAL AND REQUIRE NO CORRECTIVE ACTION: (1) "TICKING" NOISE FOR UP TO 3 SECONDS AFTER INITIAL START UP. (2) NOISE JUST AFTER OIL AND FILTER CHANGE. AIR IS PURGED OUT THROUGH NORMAL DRIVING.

1. Replace the engine oil and filter.

2. Be sure that the oil level is between "F" and "L" on the oil dipstick.

3. If the "ticking" noise is still present after replacing the oil and filter, run the engine for 8 minutes at 3000 rpm to remove any air trapped in the hydraulic lash adjusters.
